You add one side of each of the equations to form one side of the new equation. You add the other sides of the equations to form the other side.
Subtraction is done similarly.
When using the elimination method to solve a system of equations, you should add the equations if doing so will eliminate one variable. This typically occurs when the coefficients of that variable are opposites (e.g., +2 and -2). Conversely, you should subtract the equations if their coefficients are the same, which will also help to eliminate that variable. Ultimately, the goal is to manipulate the equations to create a situation where one variable cancels out.
You can use an abacus to add and subtract quantities of beads by moving the them around. This can in turn help to solve equations involving counting numbers.
The opposite of add is subtract.
When solving a system of equations by multiplying and then adding or subtracting, you decide whether to add or subtract based on the coefficients of the variables you want to eliminate. If the coefficients of one variable are opposites (e.g., +3 and -3), you would add the equations to eliminate that variable. Conversely, if the coefficients are the same (e.g., +3 and +3), you would subtract one equation from the other to eliminate the variable. The goal is to simplify the system and isolate one variable for easier solving.
You add or subtract only the numerators
You add or subtract, as required by the equation!
Equate the coefficients and subtract or add to find the value of the the given unknown variables.

does how many mean add or subtract
multiply= you add the exponets together and keep the same base divide= you subtract the exponet and keep the base the same
The opposite of add is subtract.
it means to subtract
